COMPUTERS ARE RUBBISH

i am using something called R to do what i sometimes laughingly refer to as my 'work'. it seems to have been designed by some sort of monty python/kafka hybrid to cause irritation first, and do adding up second.

things like this, for example, make me want to bite someone:

> knn1(DItrain,DItest,DIclass)
Error in knn1(DItrain, DItest, DIclass) : DItrain and DIclass have different lengths

> length(DIclass)
[1] 404

> length(DItrain)
[1] 404

why do computers think it's funny to behave like this? if your employee started coming up with responses like this, you'd sack them, or have them shot, depending on local traditions. you certainly wouldn't think "hmmm, deep. maybe there's something i'm still not understanding, i'll ask the question in a slightly different way."

computers ruling the world, my absolute bottom
